·JRV: I am following your tech
JRV: I am following your tech section on the balance, etc, for the Boxer.
I wanted to do this, because, when one stands behind the car, one can just smell the "rich" exhaust.
The car had a major service in '01, with new wires, plugs, injectors, and cleaned fuel distributors. The car now has about 2K miles more on it, since then.
Using the vacuum gauges, I was able to balance the manifolds evenly, to 15 in Hg.........they where only slightly off.
Using the gas analyzer, I came up with the following figures:
Right; CO = 0.48-0.55........HC = 300, with spikes to 500.
Left; CO = 0.48..............HC = 340, with spikes to 500.
The manual calls for CO to be around 0.9%.
Since it already smells "rich", if I increase the CO to 0.9%, won't the HCs go up as well?.....and the smell will even be more obvious?
Did the previous tuner compensate for something, by leaning it out to 0.4%?.....thus, trying to keep the HCs down?
Could the plugs be fouled due to driving the car 2K miles, thus the present readings?
I am unsure where to go next.
BTW: The car runs very well.
Thanks
